A conservation program in Western Australia has led to a record number of sightings of the critically endangered woylie, a native marsupial. The program, initiated by the Department of Biodiversity, Conservation and Attractions, has trapped and tagged 34 woylies with GPS tracking anklets, compared to just 2 sightings in 2019. Woylies are considered ecosystem engineers, similar to bison and beavers, as their digging for roots and tubers alters the entire ecosystem. The program also focuses on managing feral foxes and cats, which have posed a threat to Australia’s native wildlife. Additionally, the program has seen a growing number of Western quolls, another endangered marsupial.
